This has nothing to do with exercise, but the University of Wisconsin Hospital and Clinics (around the time i was dx) tried to sort of experiment on CFers. They told some families that their children had CF and they didn't tell the others, trying to see if the symptoms were worse or better if the patient didn't know about it... creul, and unfortunatly, they took it too far and many of the "geunie pigs" passed away. Anyway, i think this would be cool on a small-scale. Like, if having a "better attitude" versus pesimisstic thoughts about your health will help. this isn't probably what your looking for, but i think it'd be cool.
